    Improving the Use of Subscores on a Test Battery: Some Reliability and Validity Evidence from the Wechsler Intelligence Scale for Children- Fourth Edition
    (2015-05) Huang, Lan
    It is widely believed that subscores can give us more information about an examinee. Thus they can be useful in planning instructional and remedial efforts, or making vocational or academic placement decisions. However, past research has shown that subscores are often not as useful as hoped either because they do not have high reliability or because they seem to add little information. This dissertation investigated if there is any evidence of reliability and validity of the subscores from the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). The dissertation is composed of three separate studies using three empirical data sets. In the first study, we investigated the reliability issue of subscore differences and concluded that difference scores can be reliable. In the second study, we proposed two graphical methods to help with latent variable interpretation and the construct validation of subscores that are based on factor models. One way to use subscores is to do profile analysis. In the third study, using subscores from a special population and a profile analysis technique, we found profile patterns are useful in differentiating cases in various diagnostic categories and profile patterns actually outperformed profile levels.

    (University of Minnesota Tourism Center, 2007) Schuweiler, Andrea; Schneider, Ingrid E.
    In 2007, the University of Minnesota Tourism Center (UMTC) was contracted to profile visitors to St. Paul Festivals, including the Flint Hills International Children’s Festival. Visitor demographics, information sources for the festival, experience, and familiarity with community were of specific interest. As the Ordway had both a questionnaire and sampling methodology in place, the UMTC served as data analysts. The study methods and results are presented below and followed by a discussion.

    (University of Minnesota Tourism Center, 2007) Schuweiler, Andrea; Schneider, Ingrid E.; Salk, Raintry
    In 2007, the University of Minnesota Tourism Center (UMTC) was contracted to profile visitors to Rice Street Festival. Several visitor characteristics were of interest beyond demographics, including information sources, spending habits, and experience at Rice Street Festival. To that end, a visitor questionnaire was developed and administered to Rice Street Festival visitors.
